I'am unable to install the official MyJDownloader Chrome addon, due to the forced switch to manifestV3, what can I do about it?
The background:
Google decided to drop support for "manifestV2" in favor of "manifestV3" which makes our addon [officially] incompatible with the current Chrome versions.
This means that a lof of older addons won't be usable at all anymore for several reasons which include:
In our case, our MyJD addon is using features which are not possibly to do anymore via manifestV3.
Do a websearch on "Chrome manifestV3" if you are interested to find out more about this topic.
Possible solutions
The easiest solution is to switch to another browser that continues to support manifestV2 for example Firefox.
If you do not want to fully switch to another browser, you can also get a portable version of a manifestV2 supported browser and use that only for the MyJD addon.
Important: If you decide to use another browser and if that browser is not your systems' default browser you need to configure JD to use a non-default browser for captcha solving.
